I need help removing a battery from a 2005 Chrysler 300.?

I located the battery in the trunk and removed the cables from the battery post. I am not sure what to do next. The battery is still bolted in somehow.
Which bolt(s) do I remove?
I see a silver plate with a bolt in it. But there is a black bar with bolts in it running along side the battery.

I'd take the bolt out that secures the battery to the vehicle (ugh the hold down) and Simply remove the battery.
